Prokaryotes

- Single celled

organisms- No membrane

bound organelles- ex: no nucleus or

mitochondria

- Free floating DNA

- Bacteria are

prokaryotic

Eukaryotes- Single or

multicellular organisms

- Much bigger than prokaryotic cells

- Have membrane bound organelles- ex: nucleus,

mitochondria- DNA is packed

tightly in the nucleus

- Animals, plants, protists, and fungi are eukaryotic

What do prokaryotes and eukaryotes both have in

common?

•Cell membrane•Both contain DNA•Cytoplasm•Ribosomes

An organelle (small organ) is a specialized structure inside of the cell. There are many

different kinds and all have different functions.

Cell Membrane

Function:

Found in animal or plant cells: Found in prokaryotes or eukaryotes:

1.Separates the inside and outside of the cell

- Semi-permeable

Both

Both

Cell Wall

Function:

Found in animal or plant cells:

Found in prokaryotes or eukaryotes:

Rigid wall that protects the cell

Plants

Both

Cytoskeleton

Function:

Found in animal or plant cells: Found in prokaryotes or eukaryotes:

1.Framework of the cell2.Made of microtubules

(hollow) and microfilaments (solid)

Both

Both

Function:

Found in animal or plant cells: Found in prokaryotes or eukaryotes:

1.A gel-like substance that is found inside the cell

2. Organelles float in it

Both

Both

1.Controls all activities in the cell

2.Contains DNA

Function:

Found in animal or plant cells:

Both

Found in prokaryotes or eukaryotes:

Eukaryotes

Ribosome

Function:Protein Synthesis

Found in animal or plant cells: Both

Found in prokaryotes or eukaryotes:Both

Function:1.The site of cellular

respiration- Makes ATP

2. The powerhouse of the cellFound in animal or plant cells: Both

Found in prokaryotes or eukaryotes:Eukaryotes

Chloroplast

Function:

1.Site of photosynthesis- Makes food

Found in animal or plant cells: Plants

Found in prokaryotes or eukaryotes:Eukaryotes

Endoplasmic Reticulum Smooth ER

Function:1.Lipid Synthesis2.Regulates Calcium3.Removes ToxinsRough ER Function:1.Manufactures

proteins and ships them

2.Covered in ribosomesFound in animal or plant

cells: Found in prokaryotes or eukaryotes:

BothEukaryotes

Function:Packages proteins

for export from the cell

Golgi Apparatus
